I fooled around with one of my fellow band members, but he has a gf. I told him I would be willing to have a t******** with him and his gf and I guess it made him excited so we ended up sleeping together; and then later that SAME day we all went out partying and came home and had a t********. His girlfriend STILL doesnt know that just hours before we all had a t******** him and I had s**, at his parents house. Now I feel weird because she deserves to know shes dating a cheater but I cant tell her because she would kill me and he would kill me. I want to scream my secret to everyone because its bothering me. Either way if I keep my mouth shut or tell the truth I lose either way.
